AB  - The aim of this work was to study the effects of plastics (high-density 
      polyethylene (HDPE), polystyrene (PS), polypropylene (PP), and polyethylene 
      terephthalate (PET)) on reactor performance and microbial communities during 
      acidogenic fermentation of food waste for the production of volatile fatty acids 
      (VFA). The addition of HDPE and PS increased total VFA yields by 28% and 47%, 
      respectively, whereas the addition of PP and PET decreased total VFA yields by 6% 
      and 2%, respectively. The highest enhancing performance of PS could be ascribed 
      to its highly porous structure that could provide immobilization effects for 
      microbial growth. Degradation of various plastics was confirmed by FESEM results, 
      but the degrees were limited (i.e., 3.9-8.7%). Bacterial analysis showed that the 
      addition of various plastics altered the community diversity. Phylum Thermotogae 
      and genus Defluviitoga dominated all the reactors. Potential HDPE- and 
      PS-degrading microbes could belong to genus Clostridium_sensu_stricto_8, while 
      Tepidanaerobacter_syntrophicus could be PET-degrading microbes.
